Title: Light emitting diode
Inventor: MATSUMOTO KENJI
IPC: B41J2/44
Filed: 1990-09-21
Abstract: PURPOSE:To make light output hard to be changed by change of an operation temperature by taking out to the outside direct light from a light emitting layer, which changes light strength and a spectrum depending on the temperature, and reflection from a reflector having a light wavelength dependence characteristic to compensate for the changes of the light strength and spectrum by the temperature. CONSTITUTION:A light emitting layer 13 and a window layer 14 are formed on the upper face of a distribution type reflector 12 consisting of many layers of semiconductor films of different refractive indices. Light consists of light A emitted by the light emitting layer 13 and radiated outside directly through the window and light B traveling toward a substrate 11 from the light emitting layer 13, reflected by the distribution type reflector 12, and radiated outside. The light A radiated directly from the light emitting layer 13 weakens as the temperature rises but the light B reflected by the distribution type reflector 12 strengthens as the temperature rises. Therefore, the temperature characteristic of the strength is evened out and the effects of rise of the temperature are cancelled because the light taken outside a light emitting diode 10 consists of the light A and light B.

Title: Drive unit by oil pressure closed circuit
Inventor: OSHINA MORIO
IPC: F04B49/00
Filed: 1989-09-29
Abstract: PURPOSE:To prevent receiving effects OF oil temperature by composing a drive unit in such a way that an electric signal is outputted to an electric oil pressure converting means based on a detection signal of a motor resolution number so as to satisfy the relation of a differential pressure to a predetermined motor revolution number. CONSTITUTION:When a changing signal is applied to a solenoid part 14S of a direction control valve 14, the valve 14 is changed to a position (f), and the primary pressure of an electromagnetic proportional reduced pressure valve 31 (electric oil pressure converting means) is guided to a right chamber 17a of an inclined rotation cylinder 17, while the secondary pressure is guided to a left chamber 17b. A piston 17c of a cylinder 17 is displaced left for the differential pressure (secondary pressure - primary pressure) of the valve 31 to discharge pressure oil to a main conduit 18A. The secondary pressure of the valve 31 is adjusted by an output of a valve drive signal having a preset relation from a controller 34 to a solenoid part 31S of the valve 31 based on a pulse signal from a revolution number senser 33 corresponding to the revolution number of a motor 13. The differential pressure of the valve 31 is thus used, so effects of oil temperature are not given. The relation between the motor revolution number and the differential pressure is set as desired.
